Abstract: PURPOSE:To prevent a television signal of a CATV channel from being converted into a frequency viewed by a conventional television signal when a charged broadcast without any viewing contract by operating a frequency conversion circuit in interlocking with the channel selection operation selecting a channel and stopping the operation of a frequency conversion circuit when the broadcast of the selected channel is the charged broadcast. CONSTITUTION:In operating a channel selector 4, a switch circuit 13 is changed over in the state that a frequency conversion circuit 6 is in operation and since a selected television signal is subject to frequency conversion, the reception is enabled. When the selected television signal is, however, a charged broadcast, a descrambler 9 detects program contract information and when it is non- contract information, a -12V set signal is outputted from the descrambler 9 to a holding circuit 12, which is set when the set signal is inputted to output a signal -12V to an electronic switch 13. When the signal -12V is inputted from the circuit 12, the electronic switch 13 is turned off and a local oscillator 7 stops its operation because the drive power supply is interrupted.

Inventor: ARITA HIROSHI
IPC: G03B17/56
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To always optimally perform best focusing correction regardless of a used posture state by changing the value of a best focusing correction amount based on an output from a posture state detection means by an arithmetic means for putting in correction by using the best focusing correction amount stored in a storage means. SOLUTION: A controller managing the sequence of a camera having a ROM or the like in which a best focusing correction amount is stored, puts in an correction amount for every focus detecting point at a step #101. At a next step #102, whether or not the posture state of the camera is at a normal position is discriminated. When it is at the normal position, the operation progresses to a step #103 and each of the correction amount '+10' or '-10' is added further to a focus detected result F2DEF at an upper focus detecting point F2 and a focus detected result F3DEF at a lower focus detecting point F3. By constituting such algorithm to put the correction in the correction amount of the best focusing correction further according to the posture state of the camera, the appropriate focusing is always obtained without depending on the posture state of the camera.

Abstract: PURPOSE:To form compound semiconductor crystal by selectively eliminating compound semiconductor crystal formed on a high temperature decomposition oxide film, after oxide films whose decompostition evaporation temperatures are different are formed and compound semiconductor crystal constituted of different kind of atoms is formed. CONSTITUTION:A high temperature decomposition oxide film 12 is formed on an Si substrate 11. A resist film having a specified pattern is formed on the film 12, which is formed in a specified pattern by using the resist film as a mask. A low temperature decomposition oxide film is formed on the Si substrate where the high temperature decomposition oxide film, an SiO2 film, is eliminated. The substrate 11 is arranged in a vacuum vessel and heated in the manner in which CdTe source does not reach the surface of the substrate. The low temperature decomposition oxide film is easily decomposed and evaporated. The film 12 is not decomposed and evaporated and remains as it is. CdTe crystal 22 is formed by making evaporation component of CdTe source reach the substrate 11 surface. Thereby crystal which is partially isolated by the SiO2 film as the high temperature decomposition oxide film is obtained on the substrate. In said crystal, HgCdTe crystal is selectively grown to form a photo detecting element. Thereby an element-isolated photo detecting element can be easily formed.
